CONSTITUTION:A hoisting 2 with two systems, that is, an ascent-exclusive system and a descent-exclusive system, is hangingly provided at the flat area of temporary lifting equipment similar to an existing high-speed lift. In this ascent-exclusive or descent-exclusive hoisting 2, plural trucks 20 loaded with material move to the specified floors. The truck 20 reaching the floor is placed in the state of travelable onto the floor by the operation of a draw bridge disposed at the hoisting entrance of the floor.
